Important: The stats package has been deprecated. Use the superseding package Statistics instead.

The function tallyinto of the subpackage stats[transform, ...] groups the items of data into the pattern given by partition.

The values (see transform[statvalue]) in the result are the values that were in partition.

If there are data items that do not fit into the given pattern and the parameter extra gives a name, then they are put into the name specified by extra. If the parameter extra is not specified, an error condition is raised which gives the non-conforming items.

Remember that for the stats package, the upper boundary of a class (or range) excludes the boundary. So the class $3..4$ represents points $x$ satisfying $3<=x<4$. Refer to stats[data] for more information.

To regroup data, use stats[transform, tally] and stats[transform, statsort].
